Real-Time Stochastic Terrain Mapping and Processing for Autonomous Safe Landing
Kento Tomita, Koki Ho
Onboard terrain sensing and mapping for safe planetary landings often suffer from missed hazardous features, e.g., small rocks, due to the large observational range and the limited…
Cislunar Space Situational Awareness Constellation Design and Planning with Facility Location Problem
Yuri Shimane, Kento Tomita, Koki Ho
Driven by the surmounting interest for dedicated infrastructure in cislunar space, this work considers the satellite constellation design for cislunar space situational awareness (…
Generalizing Space Logistics Network Optimization with Integrated Machine Learning and Mathematical Programming
Koki Ho, Yuri Shimane, Masafumi Isaji
Recent growing complexity in space missions has led to an active research field of space logistics and mission design. This research field leverages the key ideas and methods used…
Sensitivity Analysis of Separation Time Along Weak Stability Boundary Transfers
Isabel Nolton, Kento Tomita, Yuri Shimane +1
This study analyzes the sensitivity of the dynamics around Weak Stability Boundary Transfers (WSBT) in the elliptical restricted three-body problem. With WSBTs increasing popularit…
Deterministic Multistage Constellation Reconfiguration Using Integer Programming and Sequential Decision-Making Methods
Hang Woon Lee, David O. Williams Rogers, Brycen D. Pearl +2
In this paper, we address the problem of reconfiguring Earth observation satellite constellation systems through multiple stages. The Multi-stage Constellation Reconfiguration Prob…
